DATA TRANSFER
The universal control module transfers information directly over
the EMS CX³ bus and can be used to transfer data to an operating
system.
As seen on page 42 («Viewing data»), information is available on
the mini-configurator Cat.No 4 149 36, the touch screen
Cat.No 0 261 56, the Energy Management software
Cat.No 4 149 38/39 and the Enegy Web Server
Cat.No 4 149 47/48/49.
The Modbus register tables are made available for use by a
system integrator.
In this case, an CX³ EMS/RS485 Modbus interface is needed.
ADDRESSING
Addressing can be done:
■ Locally on the product
- addressing from 1 to 9 using a selector.
■ Via softwsare
– addressing from 1 to 247,
– the selector then stays on 0.
The specifications for connection to the CX³ EMS bus are
common to all CX³ EMS devices and are described in the
product technical data sheets.
Local setting using the selector takes priority over
software setting. In the event of malfuntion, check that
the selector is definitely on zero.
